This should be a liquid width div, flush against the right hand side, with 250px of space on the left hand side. In IE5/Mac, there is sometimes a little bit of space at the right hand side, especially if you resize the window after loading the page. (This is the only one that OmniWeb 4.1b4 messes up, assuming no padding is used.)

This should be a fixed-width div, flush against the right hand side. This is correctly rendered in IE5/Mac but there is still a horizontal scrollbar, even when it is the only thing on the page.

This should be a fixed-width div with a paragraph inside, flush against the right hand side. This is correctly rendered in IE5/Mac but there is still a horizontal scrollbar, even when it is the only thing on the page.

This should be a fixed-width div flush against the left hand side. This is correctly rendered in IE5/Mac without generating a scrollbar.

This should be a fluid-width div flush against the left hand side and right:250px. It is rendered incorrectly: shrinking to fit its content if there is no block element inside it, or stretching across the whole viewport if it does contain a block element.

This should be a fluid-width div flush against the left hand side. It has margin-right:250px instead of right:250px, and this seems to fix the problems of the previous DIV. You also need right:0px; to make sure it’s right in Mozilla.

Finally, this is a div with both left and right set. (You’ll need your browser window at least 600px wide to be able to see much.) IE 5 gets this wrong, putting the right edge of the div at the right edge of the screen, while OmniWeb makes the div the same width as the viewport, pushing it out over the edge of the screen.
